IPC: B65H45/101
Filed: 1969-09-30
Abstract: 1,224,404. Finishing fabrics. H. AFFUPPER. 30 Sept., 1969 [11 Oct., 1968; 12 Oct., 1968], No. 47977/69. Heading D1S. A continuously supplied flexible textile strip 1 is folded and packed by feeding the strip 1 through a supply nozzle 2, reciprocating the nozzle 2 transversely to the supply direction to wind the strip around two substantially parallel winding pins 3, 4, and withdrawing each pin from the path of the nozzle 2 as the nozzle approaches the pin during its outward movement and returning the pin to its initial position before the inward return movement of the nozzle. In one embodiment. Fig. 1, the strip 1 is folded in zig-zag fashion in a U-shaped channel 5 and is attached at one end to a retractable plate 7 'biased inwards by a spring 6. The nozzle 2 is guided along a figure-of-eight path 8 and, when the nozzle is in the section a thereof, the pin 4 is retracted upwards or downwards, and, when the nozzle 2 is in the section b thereof, the pin 3 is retracted. The pins 3, 4 are mounted so as to be movable vertically in a frame 21, Figs. 11 and 13, containing a carriage 22 carried by rollers 23, 24 and carrying cams 25, 26 which control, by rollers 27 and rocker arms 28, the vertical movements of the pins 3, 4. The carriage 22 bears a strip supply channel 29 having an outlet nozzle, Fig. 12, and mounted so as to be displacable against springs 30. The movement of the channel 29 is controlled by cams 31, 32 acting on a roller 33 on the channel 29. During the outward movement of the carriage 22, the roller 33 bypasses the cams 31, 32 and, during the inward movement, the roller 33 cooperates with one cam to retract the nozzle 2 to form a loop of the strip about the corresponding pin 3 or 4. In a modification, Fig. 6, a supply nozzle 12 reciprocates along a rectilinear path and, during theoutward movement of the nozzle, the winding pins 13, 14 describe a square path in front of the surface of the last-tensioned section of the strip.

Filed: 1972-10-19
Abstract: 1412134 Controlling lifts PROJECT & DESIGN CO (REDCAR) Ltd 14 Jan 1974 [19 Oct 1972] 48107/72 Heading B8L A system for controlling the starting and stopping of a lift movable along a track associated with stairs, wherein oscillating electromagnetic flux signals emitted from an emitter coil on the lift, are received by a detector extending along the track, and are amplified to control the lift motor. The detector is terminated adjacent the ends of the track causing automatic cut off of signal, and hence motor, at the track limits. The control signals for up and down movements of the lift are isolated from each other, either by having two spaced emitter and detector arrangements, or by having one detector with two emitters of different frequency or polarity signals, or by having one emitter capable of emitting signals of different frequency or polarity, in conjunction with two detectors. The emitting of signals is controlled by a manually operated switch or switches on the lift, the signals ceasing as the switch or switches are released. Upon termination of the signals, a D.C. injection braking system is automatically operated within the electric lift motor. The lift is raised and lowered by a cable wound on a drum driven by the motor through a worm reduction gear-box, which worm acts as a brake once the motor has been stopped.

To produce a stream of electrons said first and second electrodes 4 and 5 are made cathode and anode, respectively, and said portion 28 extends about one-third of the distance to said mesh. To produce a stream of ions the electrodes 4 and 5 are made anode and cathode, respectively, and said portion 28 extends about one-half of the distance to said mesh. An enclosure formed by a glass cylinder 1 and earthed aluminium end-plates 2 and 3 is evacuated by a pump 20 to a pressure of 100- 300 microns Hg, which pressure is then maintained by adjusting a valve 22 to admit sufficient air to the enclosure through apertures 9 in electrode 4 to balance -the capacity of the pump. Tubes 10 and 17 supporting electrodes 4 and 5 are separated from an insulating tube 11 by copper wire spacers 12 and 18. Material 24 is vaporized in a rotatable crucible 25 by an electron beam 23 focused by an electrode 27 and condenses on a surface 26 which may be movable and may for annealing purposes be subjected to a further stream of electrons from a second similar electrode system. The cathode plate 6 may be pre-heated -by radiant heat or by conduction from a heating resistance to prevent glow to arc transitions during the initial stages of operation.

The binder may be applied after deposition on the support or by means of the liquid of the suspension which is a solution of the binder. In a preferred embodiment the support may be in the form of an endless belt 5A which passes round a roller 6 at the surface of the suspension 2 in a duct 1. Alternatively an auxiliary foil 5B may form the support and pass round the roller 6 with the endless belt 5A. The fibres in the suspension may be aligned by means of a stream of air from a pipe 4, which stream skims the surface of the suspension. In a preferred embodiment, the fibres are aligned transversely to the direction of movement of the support; to align the fibres in the direction of movement of the support an air stream is directed transversely of the direction of flow of the suspension. The remaining liquid of the suspension is driven off by heaters 7 and a binder, e.g. an epoxy resin, is added in liquid form at 8. The carrier liquid of the binder is driven off and the binder prehardened by radiation heaters 9. The resulting strip 10 is wound on to supply reel 13. The specific gravity of the liquid of the suspension is preferably 10-30% higher than the specific gravity of the fibre material. The binder may be present in the suspension in a dissolved or emulsified state. Suitable fibre marterials stated are silicon carbide, silicon nitride, aluminium oxide, aluminium borate, beryllium oxide, boron' oxide, boron nitride, metal carbide, graphite and asbestos. Suitable liquid for use as the suspension include diiodomethane, dibromomethane, 1-2-dibromomethane, tridibromomethane, aqueous solutions of thallium formate-malorate, zinc stearate or mixtures such as methylene: iodide with carbon tetrachloride or benzene. The resultant strip material may be wound on a jig and hardened or several strips may be layered and moulded to the appropriate article. The fibres are preferably in whisker form.

Abstract: 1,185,587. Laying wire. STANDARD TELEPHONES & CABLES Ltd. 23 Oct., 1968, No. 50375/68. Heading B3A. [Also in Division H3] Wire is layed between points on a substrate, which may be a "waffle iron" ferrite storage plate or support electronic components or circuitry, by imparting relative movement in at least one direction in a plane between the substrate 3, Fig. 1A, and a hollow stylus 2 through which the wire 34 is fed by driven rollers 33, 41, the wire being anchored on or adjacent the substrate at its free end and having its tension where it enters the stylus controlled by regulating the rate at which the wire is fed in relation to the rate of relative movement between the stylus and the substrate. The stylus forms part of a balanced head 5 which is suspended by two flexure springs 10, 11 from a support 1 for movement in a single vertical plane. The stylus is raised in the vertical direction whenever an armature 23 is attracted by energizing an electromagnet 14. The support carries an electric drive motor 36 for the rollers 33, 41, and is itself pivotally mounted on a support arm 24 so as to enable coarse adjustment of the stylus position to be made by moving adjusting screw 26. Two forms of stylus are described, Figs 4 and 5 (not shown), each having a radiused inner surface at the end 43 adjacent the substrate, one form having a conical bore which reduces in the direction of wire movement while the other comprises an apertured dish-shaped shoe. As applied to a substrate consisting of a waffle iron storage plate, the substrate is itself attached to an insulating base 4 supporting terminal posts aligned with the plate grooves, Fig. 3 (not shown). Wiring is effected by securing the free wire end to a terminal post and moving the substrate in directions such as to lay the wire in the required wiring pattern in the grooves and between the posts, the electromagnet being energized each time the stylus is to be raised from the base on to the surface of the substrate and vice versa. A plurality of wire feeds and styli may be used.
